Problem with the action tag

[pajarokillo]

Hi!, i have the following problem, in my struts-config.xml i have the next configuration for a Action:

<action path="/login" type="com.icg.merlin.actions.LoginAction" name="loginForm"
validate="true" input="/login.jsp" scope="request">
......
.....
</action>

i want that when my Action class throw an error, it could called to the page that i set up in the input property of the action tag.

Then, in my Action class i had put the next code when occurr an error:

return (mapping.findForward(mapping.getInput()));

but it return a blank page, what is the problem??

I wait that i could had explained well, my english is not good

getInput() only returns context-relative path of the input form, but not the logical name for forward instance for the input page that's require in findForward(). so findForward() return no ActionForward in your case and struts returns a blank page.

try use getInputForward() instead. i.e.

return mapping.getInputForward();

In your struts-config.xml file, add input attribute (path to the login jsp page) to login action mapping:

<action path="/login" type="com.icg.merlin.actions.LoginAction" name="loginForm"
        validate="true" input="/login.jsp" scope="request"
     [COLOR=red]input="/login.jsp"[/color]>  
   .....
</action>

In your LoginAction class, you would do some like this:

public LoginAction extends Action {

 public ActionForward execute(
                              ActionMapping mapping,
                              ActionForm form,
                              HttpServletRequest request,
               	              HttpServletResponse response)
		throws Exception {
     boolean loginSucess = false;

     // TODO:authenticate user
     // ....
     if (loginSucess) {
     } else {
       // this will forward to input page as defined in 
       // the input attribute in the action mapping
       return mapping.getInputForward();
     }
   
 }
}
